Tyson’s emotional visit with ailing Charles chronicled on CNN

Recent-hall-of-fame inductee Mike Tyson’s emotional visit with dear friend Nick Charles, a veteran boxing commentator who is battling advanced bladder cancer with wisdom and grace, is chronicled in a special Father’s Day weekend edition of Sanjay Gupta MD that will air on CNN June 18 and 19.

Charles, a former CNN sports anchor who knows that he is living on borrowed time, talks to CNN chief medical correspondent Dr. Sanjay Gupta about making peace with old regrets, saying goodbye to friends and preparing his family – most of all his young daughter, Giovanna – for life without him.

During the moving and revealing profile, Charles meets with old friend and former heavyweight champ Tyson to talk about some of the lessons he's still learning about living during this fight.

The Charles episode of Sanjay Gupta MD airs at 7:30 a.m. ET on Saturday, June 18, and on Sunday, June 19, only on CNN.
